SPINNING, TWISTING, AND ANAITOGOUS MACHINE.

Application filed September 19, 1913.

To all whom it may concern:

Be it known that we, SUGDEN SHACKLE- 'ron and HERBERT SHACKLETON,subjects of the King of Great Britain, residing at Malsis Mount,Keighley, in the county of York, England, have invented certain new anduseful Improvements in Spinning, Twisting, and Analogous Machines, ofwhich the following is a specification.

This invention relates to spinning, twisting and analogous machines ofthe kind in which dotting is effected by means of horizontally movablecarriers operated by rackand-pinion mechanism, and the invention has forobject to provide a more compact construction affording betterprotection than heretofore to some of the parts and generallyfacilitating the manipulation of the mechanism. v

Accordingto the invention the tin-board is movable vertically andnormally screens the carriers for the caps or fliers, as the case maybe, which, together with their operating gear are situated in rear ofsame; said tin-board being adapted to be lowered when it is desired tobring the carriers forward for the purpose of dofiing.

In the accompanying drawings which illustrate the invention by way ofexample, Figure 1 is a vertical section showing the invention applied toa well-known form of cap spinning machine. Fig. 2 is a similar view ofthe upper portion of the machine showing the tin board in its loweredposition. Fig. 3 is a front elevation of the machine, some of thespindles and other elements being omitted to expose the raising andlowering gear behind.

'leferring particularly to the drawings, 1 denotes the tin-board onwhich the usual tins 2 are mounted, carried by brackets 3 formed on, orotherwise attached to, the upper extremities of rack pillars & arrangedin guides 5 formed on guide pillars 6 which are disposed at suitableintervals lengthwise of the machine. These rack pillars 4 engage pinions7 mounted upon a shaft 8 extending longitudinally of the machine.

Atone extremity of the shaft 8 there is carried a drum 9 over which thewire ropes 10 and 10 are passed, which wire ropes are stretched overpulleys 11 and 12 and around a drum 13 carried by a shaft mount-Specification of Letters Patent.

ed in bearing 14: on the end frame 15 of the machine and provided withan operating hand lever 16, or its equivalent.

In rear of the tin-board 1 are arranged the carriers 17 for the caps 18(or fliers) which carriers are mounted on a bar 19 extendinglongitudinally of the machine and borne at the front extremities ofrack-bars 20 operated by pinions 21 in the well known manner. Said bar19 may also be provided with a row of downwardly depending pegs 22serving, in the known manner, to accomr modate the bobbins during theirtransference to or from the spindles. Below these downwardly dependingpegs 22 there may be a series of bobbin supports 23 carried by a rod 24capable of longitudinal movement so as to place said supports beneathany bobbins which may for the time being be on the pegs 22. All theseparts, such as the carriers 17, bar 19, rack-bars 20, pinions 21, pegs22 and supports 23, are situated behind the tin-board 1 which thereforeprotects them from being fouled by loose fibers and the like.

If the carriers 17 are intended for supporting caps they are of saidbifurcated type having thread guides across the open ends of same. Ifdesired the tin-board 1 may be slotted to accommodate the thread guides.

As the actual operation of dofling and the means for performing sameform no part of the present invention no description is necessary, butit will be understood that when dofling is to take place, the tin'boardis lowered by means of the hand lever 16 and wire ropes 10 and 10turning shaft 8 and pinions 7, and when in its lowermost position thedotfing elements normally in rear of same are advanced and are caused toperform their appropriate functions, after which the tin-board 1 israised to its uppermost position and spinning is recommenced. The tinboard when in its uppermost position, screens the elements of thedotting mechanism located in the rear thereof and. in conjunction withthe tins, which extend between the bobbins, defines ballooning spaceswhich are completely shut off from the dofiing mechanism. The dotlingmeans in front of the tin board may be of the construction shown anddescribed in U. S. Patent No. 1079270, dated November 18, 1913, toSugden Shackleton, and it is therefore thought unnecessary to illustrateand describe it in detail. The vertical travelof the tin-board 1 is soarranged that when in the lowermost position the tins 2 come in contactwith the driving tapes and thus press down any tubes which may tend tostick on the spindles when the lifter plate is lowered.

By means of this invention the overhead parts are amply protected fromloose fibers and the like which in ordinary constructions of spinningand like machines are frequently the cause of stoppages to clear partswhich have become fouled. In addition a much less cumbersome appearanceis presented by the screening of the overhead dofling devices and theiroperating mechanism behind the tin-board.

IV hat we claim is 1. In spinning and analogous machines, thecombination of a bobbin mechanism, a tin board, separator tinsassociated therewith and normally extending behind said bobbinmechanism, the tin board and the tins defining ballooning spaces, adotling mechanism located in the rear of the tin board and normally andcompletely screened thereby and shut off from said ballooning spaces,and driving tapes for the bobbin mechanism and means for raising andloweringsaid tin board and therewithsaid tins,

ing tapeswhen lowered so as to press down any tubes that may tend tostick on the spindles of the bobbin mechanism.

2. In spinning and analogous machines, the combination of a bobbinmechanism including spindles, tubes mounted thereon, driving tapes forsaid'tubes, separator tins arranged between said tubes and above saidtapes, a lifter plate adapted to be raised or lowered, and means formoving said tins into engagement with said tapes when the lifter plateis lowered to press down any tubes which may tend at such time to stickon the spindles.

3. A machine for operations analogous to spinning, comprising aballooning space entiiely defined by separator tins and a tin board,bobbin mechanism, driving tapes for the bobbin mechanism, and means forIHOY- ing said tins and tin board vertically to engage said tapes, so asto press down any tubes that might tend to stick on the spindles, and adofiing means.

4. A machine for operations analogous to spinning, comprising incombination tapes and means including tubes on spindles driven by saidtapes, separator tins, a lifter plate, and means for moving said tins inengagement with said tapes to press down said tubes that tend to stickon the spindles when the lifter plate is lowered.

5. In combination, a ballooning space ontirely defined by separatortins, a vertically movable tin board for carrying the separator tins,doifing carrier means behind the tin board, other dofiing means in frontof the ballooning space, means for vertically displacing said tinboard,and further means for operating said dofiing means.

6. In combination, a ballooning space entirely defined by separatortins, a vertically movable tin board carrying said separator tins,dofiing carrier means behind the tin board, other dofling means in frontof the ballooning space, means for vertically dis placing said tins andtin board, and means for bringing forward the dol'ling means bebind thetin board to coi'iperate with the dofiing means in front of theballooning space.

In testimony whereof we have hereunto set our hands in the presence oftwo subscribing Witnesses.
